FORT SMITH (AP) — A Fort Smith man has pleaded guilty in the shooting death of his aunt and been sentenced to 40 years in prison.

The Times Record reported 19-year-old Dustin Trowbridge entered the plea Wednesday in Sebastian County Circuit Court and was sentenced for the February death of 25-year-old Rita Jackalynne Anderson.

Trowbridge entered the plea as part of a deal in which the charge was reduced from first-degree murder and a theft charge was dropped.

Anderson’s boyfriend, Zachary Dunn, told police that Trowbridge and Anderson were arguing when Trowbridge waved a gun in her face and Anderson slapped it away. Dunn said Trowbridge then shot Anderson in the face.

Trowbridge said the gun accidentally went off when Anderson tried to slap it out of her face a second time.
